Check the dealer locator herehttp://www.gislavedusa.com/
. Looks like almost EVERY Volvo dealer and there was a link to Vermont tire http://www.vttireonline.com/
or you can send them an email.
I used to go to a shop that was bought by http://www.mktire.com/
. The first snows I ever bought from them were Gislaved Frosts. When they wore out I switched to Nokian. For MANY years in all the tests Gislaved and Nokian went back and forth on a 1st and 2nd place rank. Then I changed cars and Gislaved was not available in my size. Nokian seems to have more size choices and pattern options. Not necessarily a good thing all the time but all the Nokian choices I tried were all good. One of my friends had the Nordfrost 2 and didn't like them as much as the original but still WAY better than all seasons. From looking at the Gislaved site that seems to be a serious limitation is size choices.
How about this place for you GTATIRES.CA
